A NATURALIST'S VOYAGE AROUND THE WORLD. By Charles Darwin, M. A., F.R.S., Author of

"Origin of Species," etc. New Edition. 12mo. Pp. 519. New York: D. Appleton & Co.  Cincinnati: Robert Clarke & Co.

The title-page of this volume reports it as "a journal of researches into the Natural History and Geology of the Countries visited during the voyage of H.M. S. Beagle Round the World." This voyage was made forty years ago, and the first edition of this "Journal" was issued about thirty years ago. It is not, however, such a book as loses value by age. Charles Darwin, much less known thirty years ago than now, was even then a careful and thorough scientific investigator, a quick and enthusiastic observer. Having then no theories to  maintain, but being simply an earnest student of nature, he was prompt to see and wise to record the facts that came before him in a voyage "round the world." The book will be read with interest, for in addition to its valuable facts, it is written in a most pleasing and popular style.
